To all whom it may concern:

Be it known that I, FRANK W. SIMPSON, a

citizen of the United States, residing at Wellington, inthe county of Lyon and State of Nevada, haveinvented new and useful Improvements in Hay Slings or Nets, of which the following is a specification. 'Thepresent invention relates to improvements 1n hay slings or nets, and is designed to be placed upon the ground or other supporting-surface to receive deposits of hay or other materials, after which the sling or net can be drawn together around the hay or other material, hoisted, and carried to any suitable point for storing or stacking the hay or-other material.

. With these. and other objects in view the invention comprises certain novel constructions, combinations, and arrangements of parts, as will hereinafter 'be fully described and claimed.

.In the accompanying drawings, Figure 1 is a top plan view of the improved hay slini or net, t e same being unfolded and stretc ed out in positionupon the ground ready to receive a load. Fig. 2 is an end elevation of the hay sling or net, it being shown with its ends drawn together as if about a load of hay or other material. Figs. 3 and 4 are enlarged detail views, partially in elevation and artially in section, illustrating the mechanlSIIl employed in'holding the sections of the slin or net detachably together.

T e hay sling or net forming the subjectmatter of the present invention is so constructed that it 'may be stretched out upon .the ground, its sections being made for the .most part of flexible material, and hay,

grain, or other materials maythen be loaded or deposited upon, the same, after which a hoisting-rope connected with the opposite ends of the net or sling may be pulled up for drawing the sling or net around the hay or other materials and elevating the whole for carrying the load to any point where it is to be deposited. The sling or net is made of separable sections which are disconnected and permitted to fall a art when the load is to be discharged from t e sling or net.

Inthe accompanying drawing, I have illustrated one practical embodiment of the invention andwill now proceed to describe the same, reference being had to said draw-.

ings.

The sling isgenerally formed of two sections 1 and '2, and. each of said sections is rovided with an inner bar 3 and an outer ar 4, connected at suitable intervals with a series of flexible cords, cables, chains, or wires, as found most desirable. The cords5, as shown in Fig. 1 of the drawings, are preferably spread somewhat more at their inner ends than at their outer ends, and for this reason the inner bars 3 are usually made a little longer than the outer bars 4. Draft or supporting meansare applied to the outer bars 4 and usuall consist of cords or chains 6, connected wit the end portions of said bars, and intermediate cords or chains 7 are applied to the central ortions of said bars.

The ad'acent ends of c ains 6 and 7 are connected y a ring 8' at each end of the device, and to these rings the fall or hoisting rope of any suitable elevating mechanism is a plied when the sling or net is to be closed a out a load and carried to another place. The said fall-rope, as 9, is generally passed through a single swivel-block or pulley 10, which is connected with one of the rings 8, as shown in Figs. 1 and 2 of the drawings, while a hook 1 1, carried by the end of said fall-rope, is carried around the load and secured in the other ring 8.

In order to properly hold the sling or net sections together and yet permit of their being easily and quickly separated when aload is to be discharged, suitable hinge and latch connections are interposed between the inner bars 3. These connections comprise brackets 12 and 13, bolted or otherwise secured to the said .bars 3 near their ends upon one side of the sling or net, and a keeper or latch member 14 and a hasp or tongue member 15, secured to the other ends of said bars 3. The parts of these connections are clearly shown on an enlarged scale in Figs. 3 and 4 of the with outwardly-extending lugs 18, 19, and 20, i I

the lugs 19 and 20 being apertured to pro-' vide bearings for a reciprocating bolt or latch 21. The lugs 18 and 19 are placed quite close together, and are adapted to receive between them the apertured tongue or projection 22 of the eye or tongue member 15. The end of the latch 21 adjacent to the lug 18 is beveled, as shown in Fig. 4, and the end of the tongue 22 is correspondingly beveled, as also shown in said figure, so that the eye or tongue 22 can be readily forced past the end of latch 21 when the said tongue is inserted between the lugs 18 and 19. The latch 21 is normally held in position to engage and lock the tongue 22 in place by means of a spring 23, which is interposed between the lug 20 and a shoulder or collar 24, secured to the said latch. One end of the latch 21 projects beyond the lug 20 and is connected with a trip-rope 25, by which the latch may be withdrawn against the action of the spring 23 when it is desired to disconnect and separate the parts. A set-screw 26 is usually provided upon the lug 20 and is adapted at its inner end to engage a flattened portion 27 of the latch '21 sufiiciently to prevent the twisting or revolving of the latch in its bearings. The beveled end of the latch is thus always properly presented to the beveled end of the eye or tongue 22.

In using the device the sections 1 and 2 are brought together, the pintle 17 being first inserted in the aperture 16, after which the eye or tongue 22 is forced into place past the end of the latch 21, the said latch then springing into the aperture in the said tongue 22. The sections will thus be locked together. The sling or net is then spread upon the ground or a floor or other support and the hay, grain, or other materials can be piled upon the device. As soon as a sufficient load is accumulated the end of the fall-rope 9 is carried over the said load from the pulley 10 and the hook I 1 caused to engage the ring 8. By pulling upon the fall-rope the ends of the sling or net will first be drawn upwardly around the load, as indicated in Fig, 2, and a continued pulling upon said rope will operate to lift the sling or net with its load and it may then be carried to the place for stacking the material or into a barn or other storage-place or to any point where it may be desired to discharge the contents of the sling or net. When the sling or net has been brought over the point of discharge, the trip-rope 25 is pulled sufficiently towithdraw the latch 21 and permit the tongue or eye member 15 to escape from the keeper member 14, when the sections will immediately fall apart allowing the load to drop from the sling or net.

In operating my device the catch at one end of the stiffening members 3 3, consisting of the eye 12 and the pin or pintle 13, are connected by a relative longitudinal movement of the stifiening members 3 3, and then the other members are swung together upon these as a pivot and secured by the spring-catch.

In doing this the hinge connection first made serves as a stop or spacing-guide to insure the proper engagement ofthe spring-catch. This and the beveling of the latch-bolt 21 and the eye or tongue 22 contributes to ease, certainty, and rapidity in securing the two parts together. The stop-bracket 18 engaging the side face of the tongue or eye 22 prevents such relative longitudinal movement-of the stiffener-bars 3 3 as will permit disengagement of the eye and pintle connection at the other end until after the spring-catch has been released by withdrawal of the latchbolt 21.

It will be apparent, of course, that such a sling or net may be used with any kind of a hoisting mechanism or elevating and carrying means.

The parts of the device are exceedingly simple and yet are very effective for the purposes desired.

The sling or net being largely of flexible material can be rolled into a small compass and can thus be easily transported. from place to place.

Although the sling or net is preferably made as shown and described, all minor changes in the details of construction accomplishing the same results are considered as fully within the spirit and scope of the invention. I

Having now described my invention, I claim as new and desire to secure by Letters Patent 1. A hay sling or net comprising two separable parts provided with stiffening members on their line of union, a catch joining said stiffening members at one end and releasable by relative longitudinal movement between the two members, and a catch at the other end of said members provided with means for its manual release.

2. A hay-sling comprising two separable parts provided with stifiening-bars on their line of union, an eye-and-pin connection between one end of said bars engaging and disengaging by relative longitudinal movement of the bars, an automatic catch for the other ends of said bars engageable by pressing the bars together, and means for manually releasing said automatic catch from a distance.

3. A hay-sling comprising two separable parts provided with stiifening-bars on their line of union, a disengageable hinge connection for one end of said bars, a spring-catch for the other end of said bars, and means for manually releasing said spring-catch from a distance.

4. A hay-sling comprising two separable parts provided with stiffening-bars on their line of union, a hinge connection for one end of said bars, and a catch for the other end of said bars comprising a spring-held bolt carried by one bar and an eye member carried by the other bar.
